Is the shirt on the shelf really made of 100% cotton? Does the apple in the supermarket only look delicious, or is it spoiled and vitamin deficient? A closer look at the molecular structure provides the answers to these questions. Near-infrared spectroscopy makes that possible. For many years, Osram Opto Semiconductors has been developing compact and particularly powerful broadband infrared LEDs for spectroscopy. In addition to the broad wavelength range, the energy efficiency of the integrated components is essential to system manufacturers, as are the compact dimensions. Osram...

Via photoplethysmography (PPG), red light and infrared LEDs can receive date from the environment and measure biometric data including heart rate, blood oxygen, blood pressure and blood sugar level. Adopting the sensing components to wearable devices enables a wider range of applications with many leading brands working on launching related products. (Image: Pixabay) A patent Apple received earlier this year describes how Apple Watch could analyze composition of water and determine the pH level of user’s sweat through the sensing components like short-wave infrared...

According to the latest investigations by TrendForce, despite the slight slowdown in wearables shipment (including smartwatches and smart wristbands), the increasing demand for improved health monitoring functions has galvanized a strong momentum in the market for wearables-related components. For instance, to raise the accuracy of health monitoring functions, wearables manufacturers are projected to utilize more green LEDs and infrared LEDs while also increasing the size of photodiodes, in turn doubling the demand for PPG. TrendForce indicates that most wearables measure b...

Osram announced that it is providing several of its components for automotive lighting and biometric identification solutions for microSNAP, Rinspeed’s concept vehicle, which will be presented at CES 2019. Rinspeed’s microSNAP is the latest version of the company’s autonomous concept car which has a chassis to contain the drivetrain and most of the IT while connecting to various body types. (Image: Osram) Outside the vehicle, microSNAP uses Osram’s Eviyos, a hybrid LED for smart headlights, which contains individually controlled pi...

High frequency operation of infrared light sources has been widely applied in automotive, industrial and consumer segments following the trend of 3D sensing. Targeting the growing market of related applications, Lumileds has demonstrated its IR LED products, LUXEON IR Domed and LUXEON IR Compact LEDs to be alternatives to VCSEL technology. Engineering teams from Lumileds and Melexis have developed an evaluation kit that allows LUXEON IR LEDs to be operated at high frequencies up to 40MHz. The intrinsic properties of the LUXEON IR...

Epistar on 21st June announced its financial results, reporting a fully utilized capacity of blue LED as well as a sustained production of AlInGaP LED despite subtle growth in both the output of light sources and the orders for LED backlighting and little possibility to raise prices of its products. The company estimated a 15% QoQ rise that could possibly push up 2Q17’s revenue close to the number in 2Q16. Epistar also expected a decent financial performance in 3Q17 supported by the chip production for LED lighting, AlInGaP LED and infrared LED.

The new SFH 4055 from Osram Opto Semiconductors is based on the company’s proven Firefly platform, used widely for LEDs in the visible spectrum. The new transmitter, Osram’s smallest side-looking infrared LED to date, has a wavelength of 850 nm and is primarily targeted at eye-tracking systems in augmented and virtual reality headsets.

Osram Opto Semiconductors now enables remote control functionality to be incorporated in a lower profile than ever before thanks to the first flush-mountable infrared LED. The compact side-looking T-shaped Midled offers impressively high radiant intensity and protrudes only fractions of millimeters from the board. An infrared transmitter can therefore now be integrated in extra-thin smartphones or tablet computers.

  Larson Electronics has released a 12 watt infrared LED light bar that can provide output and operation suitable for medical applications. The LEDLB-4E-IR-M-110V Medical Infrared LED Light Bar provides a powerful and effective source of infrared light that can operate from standard wall outlets and be magnetically installed to metallic surfaces for easy control medical applications. The use of infrared light had showed promising results in a variety of fields including neurology and dermatology, Larson Electronics has introduced its high power infrared...
